README:

  This file should be located at the top of the jdk Mercurial repository.

  See http://openjdk.java.net/ for more information about the OpenJDK.

Simple Build Instructions:

  1. Download and install a JDK 6 from

     http://java.sun.com/javase/downloads/index.jsp

     Set the environment variable ALT_BOOTDIR to the location of this JDK 6.

  2. Download and install the JIBX libraries, version 1.1.5 from

     http://sourceforge.net/project/showfiles.php?group_id=69358&package_id=68290

     You'll need the following four JAR files:

         bcel.jar

         jibx-bind.jar

         jibx-run.jar

         xpp3.jar

     Set the environment variable ALT_JIBX_LIBS_PATH to the location of

     these JAR files.

  3. Download and install the Binary Plugs for the most recent JDK7 from

     http://download.java.net/openjdk/jdk7/

     Set the environment variable ALT_BINARY_PLUGS_PATH to the location of

     these binary plugs.

  4. Either download and install the latest JDK7 from

     http://download.java.net/openjdk/jdk7/, or build your own complete

     OpenJDK7 by using the top level Makefile in the OpenJDK Mercurial forest.

     Set the environment variable ALT_JDK_IMPORT_PATH to the location of

     this latest JDK7 or OpenJDK7 build.

  5. Check the sanity of doing a build with the current machine:

       cd make && gnumake sanity

     See README-builds.html if you run into problems.

  6. Do a partial build of the jdk:

       cd make && gnumake all

  7. Construct the images:

       cd make && gnumake images

     The resulting JDK image should be found in build/*/j2sdk-image
